What are the two main types of hair color?

The two main types of hair color are permanent and temporary. Permanent hair color is designed to create a long-lasting change to the hair's natural color. It works by opening the hair cuticle and allowing the color to penetrate the hair shaft, resulting in a change that can last for several weeks or even months until new growth occurs at the roots.

Temporary hair color, on the other hand, is meant for short-term use and typically washes out after a few shampoos. It coats the outside of the hair rather than penetrating the shaft, making it an excellent option for someone wanting to experiment with color without committing to a long-lasting change.

Understanding these two basic categories helps professionals determine the best coloring approach for their clients based on desired results, longevity, and maintenance preferences. This distinction is essential in cosmetology, as it directly influences how stylists recommend products and techniques to achieve client goals.
